Description
The total number of frames discarded because of late collisions detected during transmission.
It includes all transmit frames that had a collision after the transmission of the frame's 64th
byte. The preamble and SFD are not included in the frame's byte count.
The total number of frames that failed to be sent after 16 collisions. It includes frames of all
destination address types.
Counts the number of transmit frames that were tagged with an 802.1q tag and discarded
during transmission.
Total number of bytes received by this port.
The total number of well-formed unicast frames received by a port. It excludes frames
received with errors, with multicast or broadcast destination addresses, or with oversized or
undersized frames. Also excluded are frames discarded or without a destination.
The total number of well-formed multicast frames received by a port. It excludes frames
received with errors, with unicast or broadcast destination addresses, or with oversized or
undersized frames. Also excluded are frames discarded or without a destination.
The total number of well-formed broadcast frames received by a port. It excludes frames
received with errors, with unicast or multicast destination addresses, or with oversized or
undersized frames. Also excluded are frames discarded or without a destination.
The count of received frames that were dropped.
Incremented for each MAC pause control frame received.
The total number of frames received with alignment errors. It includes all the frames received
with both an FCS error and a nonintegral number of bytes.
The total number of frames of less than 64 bytes that have an integral number of bytes and
bad FCS values.
The total number of frames received that were less than 64 octets long (excluding framing
bits, but including FCS octets) and were otherwise well formed.
The total number of frames received of more than 1518 bytes that have good FCS values.
The total number of frames received with FCS errors. It excludes undersized frames with
FCS errors.
The total number of received frames discarded because their size exceeded the maximum
allowed Ethernet frame size.
The number of frames received that are longer than 1522 bytes and have either an FCS error
or an alignment error.
The number of times the source address of good received packets has changed from the
previous value.
Incremented each time a valid carrier was present and at least one invalid data symbol was
received.
